I don't use the log in on the ssa site after checking it once. I didn't tell me anything that I needed to know, so I can't answer that one for you.

I don't believe they mix the back pay and the current month's check. Do you understand that the SSDI payment for April is paid in May ? Then the May check gets paid in June, etc.

Do you know which Wednesday of the month is your hubby's payday ?
